LPA-Series AUX IN installation
The LPA-Series receiver can connect to the AUX INPUT of a public address
amplifier if the LPA receiver is installed in close proximity to the PA amplifier.
•
The RCA phono cables required for interconnection should be no longer than 6 feet. Installations requiring
LPA receiver location greater than 6 feet from the PA amplifier must use the 600
Ω
balanced output.
•
If the AUX INPUT of the PA amplifier is already used, the LPA receiver is connected between the AUX audio
source (stereo tuner, cd player, tape player, etc.) and the PA amplifier as shown.
•
Audio from the AUX audio source will be routed to the PA amplifier as normal when the LPA receiver is not
in use. When an LPA radio message is received, the LPA receiver will disconnect the AUX audio source
and replace it with the radio transmission. Once the radio message is complete the AUX audio source is re-
connected to the PA amplifier.
•
When using the PA amplifier AUX INPUT it is important to remember that received messages from the LPA
receiver will be treated exactly the same way any other audio device connected to the AUX INPUT. On
many PA amplifiers the AUX INPUT audio is automatically muted whenever audio is present on the MIC
INPUT. Check the owner’s manual for the PA amplifier to determine AUX INPUT operation and the effect it
will have on LPA operation.
